Problema Solution

Erin logs onto her computer every four days, Don longs on every 6 days and Maria logs on every 8 days. How long will it be before all three log on the same day?

We need to find the least common multiple for 4, 6 and 8:

LCM(4, 6, 8) = 24

In 24 days all three will log on the same day.
